Question

Find the length of AC¯¯¯¯¯¯¯¯A. 33.13B. 377.19C. 378.63D. 2.89

Answer 1

The trigonometry ratios are

`\begin{gathered} SinD=(AK)/(KD) \\ \\ tanD=(AK)/(AD) \\ \\ tanK=(AD)/(AK) \\ \\ cosK=(AD)/(KD) \end{gathered}`

AD = 31

AK = 24

Since we do not have the length of KD, then

The value of sinD and cosK are wrong

Let us find tanD and tanK to check which one is right

`tanD=(24)/(31)`

But the given value is 31/24, then tanD is wrong

`tanK=(31)/(24)`

It is the same with the given value

The correct option is C
